Picking the right resale platform is a routing problem, not a price problem

Short summary

Resellers lose money listing items on the wrong platform, even when pricing is accurate. Platform selection is fundamentally a routing problem, not just price optimization—build a scoring function ranking platforms by expected net return per week of effort (accounting for fees, velocity, shippability, and brand demand). Use GPT-4o for item ID and prefer explicit, inspectable scoring over opaque ML because failures are debuggable.

• •Platform selection is a routing problem, not price maximization—wrong platform choice costs sellers real money despite accurate pricing
• •Explicit scoring functions outperform ML black boxes because production failures are inspectable and fixable, not hidden in model weights
• •GPT-4o vision identifies item category and brand; human review gates recommendations to catch misclassifications before costly listing
